Improvement in tanners  rinsing-wheels



PHILO LULL, OF N ORWIOH, NEW YORK.

IMPROVEMENT IN TANNERS RINSING-WHEELS.

Specification forming part of Letters Patent No. 119,778, dated October 10, 1871.

To all whom it may concern.'

Be it known that I, PHILO LULL, of Norwich, in the county otl Ohenango andState of New York, have invented an Improved Pin for Tanners Rinsing-Vheel, of which the following is a speciiication Figure l is a perspective view of the pin, and Fig. 2 is a transverse section of the wheel with the pin in place.

This invention relates to the pins that are attached to the insides of the hollow wheels used by tanners both for softening hides in a stream of water that is caused to flow through the wheel preparatory to subjecting' them to the action of lime for the purpose of removing the hair, and also for subsequently rinsing the lime from the l hides. The invention consists in the combination,

with such pins, ot' stone or earthen plates, one to each pin, attached to one side thereof, to enable it the better to discharge its functions.

Referring to the drawing, A is thehollow wh eel, and a are the pins that are screwed or otherwise fastened to the inside of the wheel, in circumferential rows and in quincunx order, the number and size of my improved pins depending, as in the case of thel common pins, on the size ofthe wheel, these details forming no part of my invention. An earthenware or stone plate, b, is

attached to one side of each pin a. This may be done, or the plate may be detached from the pin, either before or after the latter is inserted in the wheel. The plate, if worn at one end, may be reversed, or, if broken, may be removed, without disturbing the pin. The plates do not become smooth by use as wooden pins do, but always present the rough surface, which is essential to the best performance of the softening and rinsing operations.

The pins, with these adjuvants, do their work so thoroughly as to render unnecessary half the manual labor that has to be employed to complete the cleansing` of hides that have been operated upon by the common wooden pin. The stone plates`also effect a great savingof time as well as labor.

I am aware that scouring-stones have been set in the exterior of a tanners wheel, and I therefore do not claim the stone plates broadly; but I claim as my invention- The combination of stone or earthenware plates b with the wooden pins a of a tanners wheel, as

specied.
